The Killing alumEric Ladin is set to play young J. Edgar Hoover on HBO‘s Boardwalk Empire. Ladin, repped by Innovative and Main Title, has joined the cast of the period mob drama as a recurring. This is Ladin’s second recurring gig on an HBO series; he also had a role on Big Love as Chloë Sevigny’s doctor.

In another recurring HBO casting, Brothers & Sisters alum Luke Grimes will film five episodes of the upcoming sixth season ofTrue Blood. I hear he would be upped to a regular if the vampire drama is renewed for a seventh season. Grimes, repped by CAA, manager Darren Goldberg, and attorney Dave Feldman, will play Wes, a 27-year-old, sexy, spiritual, compassionate, intelligent, protective, deeply emotional, and guitar-playing vampire who was turned in the ‘70s. He next stars with Amber Heard in Weinstein Co’s recent acquisition All The Boys Love Mandy Lane.
